i saw one on the highway the other day and the exhaust tips were gigantic,, what kind of engines do they have , hp, torque, etc...

 

the lousy tips you probably saw were "hilbilly fix" called ...echo tips they sound like **** and are for people dont REALLY HAVE a engine...anyway forget what i just said i live in missouri almost the hillbilly capitol of the u.s.! the firehawk 4th gens run just as fast as ws6 ram air f-bodies(well maybe a tad quicker) around 13.1's or so they only make 335 hp ...just 10 more than regular ws6's! the engine is a ls1 just like the other f-bodies. the tq is around 350lbs or so.

"hillbilly fix," that is pretty funny. I live in S. Ill, it seems like every stock RS down here has those huge tips. I can think of at least three six cylinder thirdgens down here with those huge dual tips also . . .

 

There was also a LT1 Firehawk, that had around 310 hp.

I think the 4th gen Firehawks are not fast enough compared to my TTA.

 

Hope this helps I got this from Car&Driver Jan. 1998:
They compared the suspension setups for the base Formula/Trans Am, the WS6 Ram Air, and the SLP Firehawk which has 3 levels of suspension performance options. The road test was conducted on a Trans Am Firehawk, 6 speed, and the Level II Performance Suspension (Level III recommended for racing). They also had the optional Auburn differential ($899) with 3:42 gears. It did not have traction control.

Firehawk ratings:
327 bhp at 5200 rpm
345 lb-ft at 4000 rpm
[the additional 7 hp over the WS6 Ram-Air comes from the SLP low restriction exhaust - no increase in torque]

They put the car through "eight punishing quarter mile runs, the best
two of which averaged to 13.5 seconds at 106 mph. Then we drove it 15 miles
at a top speed of 158 mph. Sprints to 60 mph took five seconds flat."

For comparison they list a stock Trans Am at 0-60 in 5.3 secs, and the quarter in 13.9 sec at 104 mph.

The WU6 Firehawk package lists at $3999.
[compared to the WS6 package which lists for $3100]
Base Trans Am listed at $26,500. List price of Firehawk as tested with all options: $33,878.

They say that SLP only expects to produce about 500 Firehawks in 1998.

Bottom line the folks at Car and Drive seemed most impressed with the overall package: good looks, good performance, good handling, good ride, and nice sound.

Given the recent list discussions on F-Body future C&D said it best:
"Superlative performance, distinctive looks, and exlusivity make the Firehawk the most potent weapon in GM's pony-car arsenal. Too bad potent
weapons don't seem to win the sales war in this segment."

one of the biggest reasons gm lost sales was due to pricing. the camaros and bird have always been more from what i know... and now its a big difference. of course, over the past 15 years, gm has had a better hp motor too

My Firehawk has the optional SLP resonator exhaust and has 3 1/2 tips. If I compare SOTP performance between it and my '91 Formula which I would guess is now in the 360-375 hp range, I would have to say that the Formula pulls harder off the line, but the LS1 pulls hard all the way to the redline. If I had to make an educated guess, I would have to say with the right traction and the right launch they would both be high 12 second cars...
